This post reminds of when a young nephew wanted to know if when I squeezed the trigger on my "wash down" special gun utilizing several pumps via a common manifold & hi pressure 3 way valves. I am quoting him "does it lift you off the ground ... if you are not careful"What about an CAT 3535, any danger in hooking up a hose and gun to the pump stand?
CAT 3535 36GPM @ 1200psi - Yes you could. Just be careful with your gun nozzle size. To large and you will not be able to handle the gun for very long before you're fatigued. Make sure your unloader/regulator is working properly.What about an CAT 3535, any danger in hooking up a hose and gun to the pump stand?
Just a thought ... I wonder if the 3535 or similar pump was setup with a programmable VFD ... then a signal could be sent to the VFD when the single wash down nozzle was used changing the program to make the motor run at a different RPM. It seems like that could possibly help prevent the mentioned pump seal potential overheating problem.I'd be concerned with running a 3535 at 1000 or so PSI at only a tenth of its flow without the pump seals getting hot.
I am not sure on the bigger pump but with joining the flow via manifolds & controls with three or four Cat 310s with 3HP 3ph motors ... it sure seems not too complicated for us considering the time we save. I think the extra momentum from water volume is more effective than a narrow spray with more pressure. I do use a 75 foot 1/2 inch ID hose on a retracting reel with a the largest variable pressure KleenRite gun made for truck washes. Be forewarned 3/8" hose affects the volume of water too much from my experience.The only way a larger pump would help cleanup time is if the nozzle is much bigger. At 1800 PSI with a 1508 tip I have to lean forward on the gun against the pressure.
The pumps could get hot...but do they?If I go beyond four pumps ... I notice that there is no gain & the pumps could get hot within a pump's individual bypass hose (recommended for each Cat 310 Pump install).
At the point of four pumps ... yes there is actual warning signs of heat build up & questionable wash down gains over three. There are actually 7 pump setups available but one is a portable backup that is on wheels that is used with some quick-disconnects (both electrical & water & chemical wise) when the normal bay pump goes down. The ability to use a quick backup pump - motor combo was an integral part of the project over 25 years ago.The pumps could get hot...but do they?
You could run more bays if you had a 4016 tip.
that's really smart. i need to do that.I have one SS bay at each wash with a quick coupler at the pump. I keep a long hose with gun at each wash, with the male coupler half on that hose. Whenever needed, I just shut that bay down, uncouple the hose going to the bay, and plug in the clean-up hose. You only get HP functions, but that's all I've ever needed.
